Answer:

In the root and shoot meristem.

Explanation:

Plants have two types of tissues such as meristematic tissue and permanent tissue. Permanent tissue does not take part in cell division and differentiation. The meristematic tissues are continuously divided and differentiate into different plant parts.  The meristematic tissues are found in the tip of the shoot and tip of the root. These are continually grown and differentiate into new roots and shoots. Therefore in plants, new leaves, roots, branches and height occurs.

The efficiency of a car’s engine is 14 percent. This implies that the engine wastes
Harlamova29_29 [7]

Answer:

C) 86 J of energy for every 100 J that enter it.  

Explanation:

Efficiency is a measure of performance of an engine which can be calculated by the formula as given below to get in percentage:

           Efficiency = energy output/energy input x 100

If the efficiency of a car’s engine is 14 percent it means that for every 100 joules of energy that is entered into it, only 14 joule is converted into useful output and rest of the 86 Joules is wasted.

The efficiency of any machine is never 100%, however, if any machine miraculously converts all the input energy to useful output energy, it means it is 100% efficient.

Hope it helps!

Plants need carbon dioxide and _ out of photosynthesis
ICE Princess25 [194]
I'm not sure if this is exactly correct, but to complete photosynthesis, plants need carbon dioxide and water. Usually sunlight as well. If you are supposed to be specific, you could put H2O. I hope I answered your question!

Why does water move along its concentration gradients?
Artemon [7]
There is an electrical gradient and there is a concentration gradient.

1.) Chemical gradient better known as concentration gradient is much more powerful and compelling than the electrical gradient.

2.) Water is a polar molecule, meaning one side it positively charged while the other is negatively charged. This polar charged molecule causes water to have a weaker electrical gradient, thus the water has to move on its concentration gradient.

Which description properly describes the plant structures involved in photosynthesis?<br><br>​
Nonamiya [84]

Answer:

C Phloem transports glucose to the plant, and stomata release oxygen

Explanation:

A Stomata take in water,sunlight, and carbon dioxide and release oxygen  - this is false, the stomata are for gas exchange (taking in carbon dioxide and releasing oxygen). They do not take in water and sunlight

B Phloem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight - this is false, while it is true that stomata take in carbon dioxide, and chlorophyll absorbs sunlight. phloem does not transport water, that is the xylem.

C Phloem transports glucose to the plant, and stomata release oxygen - this is true. Stomata takes in carbon dioxide and releases oxygen, and phloem transport the products of photosynthesis throughout the plant

D Xylem takes in water, sunlight and carbon dioxide and releases oxygen - this is false. Xylem does take in water, but not sunlight, carbon dioxide or oxygen
